[vtkusers] Re: Mouse wheel events not working under Win32?

Bonjour Mathieu,

Thanks for your answer.

I am using the 4.4 version of VTK provided with the book on the CD. I am 
not using TCL wrapper for the moment, but I will do a build with it to try 
the sample you provided, but I guess they will work (regarding the 
following point).

I have more information to give: I am using a vtkRenderWindow embedded 
into a regular Windows' window (I use SetParentID). If I remove the call 
to SetParentID, a vtk window is created outside the supplied parent window 
(that's normal, ok), but the mouse wheel is know working ...  Is there any 
point I am missing ? 

I read again (and again) Charles's thread, but in his case, he is using 
MFC, so he has to overide the CView::WindowProc (that's the patch, isn't 
it), to handle the WM_MOUSEWHEEL case, but I am not using MFC, and I have 
no WindowProc to overide, and it does not seem necessary as WM_MOUSEMOVE, 
WM_LBUTTONDOWN and UP and other mouse messages are well sent to the 
vtkRWI.

Any idea ?
